Created attachment 496714 [details] X configuration file Description of problem: I am running fedora 15 on my laptop (dell precision m4500), and most of the time, an external screen is attached to it. The external screen is positioned at the right of the laptop screen. I am using the nvidia driver, and I configured it this way using nvidia-settings. I choose 'Twin View' as 'X server display configuration'; I will attach the xserver.org configuration tot this report. When I boot my laptop without the external screen attached, and when I start applications from gnome 3, some of them appear 'off screen'. (on the not-attached external screen on the left.) Version-Release number of selected component (if applicable): gnome-shell-3.0.1-1.fc15.x86_64 xorg-x11-drv-nvidia-270.41.03-1.fc15.x86_64 Steps to Reproduce: 1. Configure dual screen setup 2. Reboot laptop without external screen 3. Login to gnome 4. Start some random applications Actual results: Some applications appear off-screen Expected results: All applications appear on the available screen Additional info: A workaround: If a window appears off-screen, focus it using alt-tab, press alt-F7, and move the window on-screen using the mouse.
Erratum: the external screen is on the left, the laptop on the right. Not sure whether this is relevant.
Does it work with the free (as in freedom) nouveau driver? (the default one) -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers
(In reply to comment #2) > Does it work with the free (as in freedom) nouveau driver? (the default one) > Can you give me a pointer about how I can disable the non-free driver, and use the noveau driver instead? In the documentation, I found that then nvidia driver can be disabled using nvidia-config-display disable but nvidia-config-display doesn't seem to be on available on my system. (I am using the non-free driver because I installed it under F14, and I just upgraded my old system to F15)
yum remove xorg-x11-drv-nvidia* *kmod-nvidia* then remove xorg.conf, and everything with the name nvidia in it in /etc/X11/xorg.conf.d remove any parameter from your kernel that disables modesetting if you have such parameter (in grub.conf, if you didn't add it manually it shouldn't be there), and reboot. The free driver should be used, you should get gnome-shell, and it should work. -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers
With the nouveau driver, the problem doesn't occur. So I guess it is a bug in the nvidia driver. I think I will just keep using nouveau then. Thanks for your help!
